To aZZ wiz-0m t may concern:

Be it known that I, EMERY CoULoN, a subject of the King of Belgium, residing at Blaton, in the Kingdom of Belgium, have invented certain new and useful Improvements in Machines for Removing the Wood from Ramie-Stalks in the Green State, of which the following is a specification.

The present invention relates to machines for removing the ligneous portion of ramie stalks in the green state in order to separate the fibrous part which is subsequently intended to be 'converted -into harl, into which machines the green stalks fixed in grppers are passed by feed chains between a curvilinear anvil and a winged beater drum.

The machines of this type must be provided with a device permitting the free passage of the grippers between the anvil and the beater drum and with this object it has already been proposed to arranged the anvil above the beater drum and to provide it with a spring-controlled rod mounted in a support in which it can be displaced longitudinally in order to separate the anvil from the beater drum by means of a bent lever, one arm of which is located in the path of the grppers by which it is lifted when they pass beneath it and releases a retaining member which enables the anvil to rise. these machines t-he chains which feed the ramie stalks pass on a level with the arms of the anvil and the stalks are only sub. jected 'to the action of the beaters of the drum which is frequently insufiicient to detach the wood from the fiber. Furthermore the complication and the fragilityl of the mechanism for lifting the anvil constitutes a grave defect because the machines are intended to be employed on or near ramie plantations where repairs are diliicult and it is necessary that they should act at a high speed in order to render their use remunerative. f

The present invention has for its object r a simple and strong device which obviates this defect and which consists broadly in providing the grippers at their two ends with members intended to be introduced between a part integral withthe anvil and parts integral with the framework of the machine so as to separate the apvil from .the drum during the passage of lthe grippers. The anvil is arranged beneath the dru'm and normally it emerges above the i sufliclent interval to render it certain that they will not be struck by the'beaters ef this drum.

A machine embodying the invention is illustratedby way of example in the accompanying drawing, in which:

Figure 1 is a side 'elevation thereof. Fig. 2 is a plan and Fig. 3 is a detail View of the drum and the anvil.

In these figures a is the drum mounted on a shaft ZJ and provided with wings or beaters c. Z is the anvil integral with a plate e mounted on rods f sliding in guides g and g. Springs 71, normally press the anvil al against the beaters c. On a level `with the plate e there are arranged in front of and behind it tables z' and z" on each side of which the conveyer chains y' run. These chains are driven by pinions lc and are connected at intervals by rods Z provided with two grooves m intended for the reception of the hooks n of the grippers A in which the ramie stalks from which the wood isto be removed are fixed. Upon each of the rods Z eccentric cams or rollers o are journaled. on either side of the table i; their periphery can be provided with casters or balls o.

The plate e extends beyond the anvil d on either side thereof into the path of the rollers 0 and above the edges of the plate e guides p are fixed to the framework of the machines parallel with the plate but their extremities are raised in such a manner as to present inclined surfaces.

Upon the shaft b of the drum a there is keyed a toothed pinion g in mesh with a wheel r-mounted on a shaft r which carries a handle C or a driving pulley and also a pinion s which by means of the pinions t tf transmits its movement to a wheel u keyed upon a shaft. v journaled in the framework B of the machine this shaft 'v carries l grippers A engaged 0n one of the rods Z are of the lifted by the springs h and lilil carried toward the anvil d and the drum a the chains j. 'When the grippers reach the plate e the r llers 0 lpass between the lateral edges of this plate'andthe guides p depressing the plate and the anvil suliiciently to allow the grippers ter and the beaters of the drum a without these beaters being able to come into contact. with them. As. soon grippers A have passed beyond the rear edge plate e the latter and the anvil d are the ramie stalks are pressed against the beaters of the drum which rotates in a direction opposite to that of the displacement of the chains j. As the anvil emerges above the level of the chains the ramie stalks displaced by the latter are first of all bent and pressed against the front edges of the anvil and after they have been acted upon by the beaters of the drum they are again bent and pressed against rear edge of the anvil beforebeing deposited upon the table z". The stalks are thus acted upon on their two faces in succession as they would be by three beater drums arranged one after the other and acting alter.- nately upon the under and upper sides of the stalks. When they reach the table d the ibersof the stalks are entirely detached from their wood which becomesseparated without any subsequent beating being necessary.

What I claim and desire to secure by Letters Patent of the United States is 1. A machine for removing the wood from ramie stalks in the green state, comprising in combination rods supporting the anvil, guides integral with the framework of the machine for these rods, springs cooperating with the rods in order to hold the anvil normally above the level of the conveyer chains and means for depressing the anvil beneath to pass between the lat-V asthe rollers 0 and the each side thereof the the-level of the conveyer chains passage of the grippers carrying between the anvil and the beater drum.

Q. A machine for removing the woodfrom ramie stalks in the green state comprising in combination rods supporting the anvil, guides integral with the framework of the machine for these rods, ,springs'coperating with `the rods in order to mally above the level of the conveyer chains, a plate integral with the anvil extending on and cams fixed to the conveyer chains on either side of the grippers hold `the anvil nor-v during the the stalks c'arrying the stalks so that they penetrate between the plate and the guides of the framework in order to depress the anvil during the passage of the grippers carrying the stalks between the anvil. and the beater drum.

3. A machine for removing ramie stalks in the green state, in combination spring supports the anvil normally above the level of' the conveyer chains, anvil extending on guides integral with the framework of the machine for limiting the lifting of the plate and of the anvil and cams fixed to the outer comprising either side thereof,

sides ofthe conveyer chains opposite the grippers carrying the stalks adapted to penetratebetween the guides of the framework and the plate so as to depress the latter and the anvil when the grippers carrying the stalks pass between the anvil and the beater drum. l A
